BACKGROUND & AIMS: Despite the lack of evidence for the benefits of dietary restrictions for ulcerative colitis (UC), the majority of patients with UC restrict their diets to avoid relapses. Few studies have examined information resources that affect patients' dietary beliefs or practices, but none have investigated UC patients in clinical remission from Asia. This survey investigated the dietary beliefs, practices, and information resources of Taiwanese UC patients in clinical remission.
A self-reported questionnaire was administered. Fifty UC patients in clinical remission (defined based on having a 2-item patient-reported outcome score of ≤1 with no rectal bleeding for ≥90 days) were recruited from National Taiwan University Hospital between September 2017 and March 2018.
In total, 22 patients (45.8%) believed diet to be the initiating factor for UC, and 48.0% of patients believed diet has ever triggered relapses. Forty-two patients (85.7%) avoided specific foods to prevent a relapse. Spicy foods were the most avoided foods (75.5%), following by alcohol (69.4%), carbonated beverages (63.3%), milk or milk products (59.2%), and fatty foods (59.2%). The patients' information resources for dietary beliefs and practices consisted mainly of their own experience. Approximately one-third of the patients have avoided the same menu with their family or avoided outdoor dining to prevent UC relapses.
This is the first dietary belief survey focusing on clinical remission UC patients from Asia. Most clinical remission UC patients spontaneously avoided specific foods based on their own experiences. Dietary restrictions may negatively affect patients' social lives. Further dietary counseling is necessary to minimize the possible negative impacts on UC patients in clinical remission.
尽管溃疡性结肠炎（UC）患者限制饮食并无获益的确切证据，但大部分 UC 患者仍会限制饮食以避免复发。有一些研究调查了影响患者饮食信念或实践的信息资源，但均未调查来自亚洲临床缓解期 UC 患者。本研究旨在调查台湾临床缓解期 UC 患者的饮食信念、实践和信息资源。
采用自报式问卷，对 2017 年 9 月至 2018 年 3 月期间在国立台湾大学医院接受治疗的 50 例临床缓解期 UC 患者（基于 2 项患者报告结局评分≤1，且无直肠出血超过 90 天）进行调查。
共 22 例（45.8%）患者认为饮食是 UC 的诱发因素，48.0%的患者认为饮食曾引发过复发。42 例（85.7%）患者为预防复发而避免食用特定食物。最常避免的食物是辛辣食物（75.5%），其次是酒精（69.4%）、碳酸饮料（63.3%）、牛奶或奶制品（59.2%）和高脂肪食物（59.2%）。患者获取饮食信念和实践相关信息的资源主要来自自身经验。约三分之一的患者为预防 UC 复发而避免与家人共餐或避免外出就餐。
这是首次聚焦于亚洲临床缓解期 UC 患者的饮食信念研究。大部分临床缓解期 UC 患者基于自身经验主动避免食用特定食物。饮食限制可能会对患者的社会生活产生负面影响。有必要进一步开展饮食咨询，以尽量减少对临床缓解期 UC 患者的潜在负面影响。
